Why did the states in the Balkans prefer to fight over neighboring regions during the 19th and early 20th centuries instead of saving money to engage in overseas colonialism?

The Balkans are like the mischievous children of a family that can't govern itself. The Turks come and bring order, then when they leave, you fight each other, then the Turks come again and bring order. That's how the Balkans are. When the Turks leave and the Europeans come, they try to commit genocide. Because for European states, the Balkans are second-class citizens. So, if you're not fighting each other right now, it's thanks to the Turks. The moment we withdraw our hand, a huge war will break out in the Balkans, and Europe wants this; constant competition and chaos among you. Yes, look at your situation while the Ottomans ruled, and look at what you did after the Ottomans left, the genocide and massacres, the oppression you suffered.
